Review: Worldfit Isotrainer... trully World class! - The most affordable and versatile high quality isometric exercise equipment is now making its way into many homes, offices, and workplaces of fitness conscious individuals worldwide in the post pandemic era. • You believe that exercise is important and have been exercising for years but your joints are giving you problems. There is there a way to exercise without further exposing your joints to damage. • You are juggling several important priorities and seem to have no time for exercise? You can exercise for as little as 5 minutes a day and yet gain tremendous benefits! • Tight on the budget and can’t afford a gym membership? For a 30 + dollar investment, you can have a 2 pound world class exercise equipment that will be a constant companion on the road to strength and fitness. The Worldfit ISO-Trainer gives you the ability to do many isometric exercise protocols that results in strength and muscle gains. You can utilize overcoming and yielding isometrics as well as dynamic exercise movements. The Worldfit ISOtrainer stands at par with other more expensive world class isometric exercise equipment and complements their use. The Worldfit ISOtrainer is current with Exercise science. Isometrics once considered a protocol of an era gone by has made a comeback because exercise physiology has confirmed its effectivity along with other exercise modalities. The Worldfit ISOtrainer enables you to safely perform Isometric Exercises to progressively increase your strength, lose weight and build lean muscle mass. Its pros heavily outweighs the cons. I think the only con is that it does not measure effort and work you put in. But it would be unfair to expect that feature from this devise. The pros weigh heavily on its favor. It’s really well constructed. “Made to last” is not just marketing hype. When you lay hold of it and use it, that phrase becomes fact. Where on God’s great earth can you find such an excellent piece of isometric equipment that sells for such an unbelievable price! It mimics all the exercises you can do on some of the cutting edge isometric equipment like the Isochain which sells for almost $500. The webbing is true Ist class military grade. The handles are some of the strongest, most comfortable ones I have ever encountered The cam buckles exude quality. Learning to adjust them is a cinch and has never bothered me. You easily develop a system of learning what lengths go well with some exercises. I take them to the office and among other things start my day using these for various time holds depending on my current program. You can really push and pull for all you’re worth and it will deliver. No fear of it breaking which for fit seniors like me, is something we really value. I have three of these goldmines waiting to keep me fit in my 2 offices and my house.
Review: great tool for isometric training - For those that practice isometric training, this product is sturdy and very useful. It is adaptable - it can be adjusted to various sizes and angles to target lots of muscle groups. It comes with some recommended exercises, but you can use your imagination to use this for much wider applications. My use case for this is to stimulate muscles at extremely high intensity with minimal risk of injury (develop more mind-muscle connection), which the fixed tension and no range of motion accomplishes. It's very sturdy, so as long as it is used at safe angles for your joints and no jerky movements, then I think it's a very safe way to get some intense muscle stimulation in. I don't expect this to make me ripped, it's more of a supplemental exercise to actual weight training. Overall, I think it's a great product, I am not sure why but there's not a lot of products out there like it (and not at this great price point), even though isometrics has some pretty solid research backing it's effectiveness.

## Questions & Answers

**Q: What is the circumference of the handles?**
A: Hello John,
Thank you for your question. The diameter is about 1.38in, which brings the circumference to roughly 4.3in. Please feel free to call us directly at 925-350 -4111 should you have any other questions.
With best regards,
Your WorldFit Team

**Q: Can you do leg exercises barefoot or will the strap be too uncomfortable?**
A: I personally like to use sneakers,  but I use sneakers that I don't wear outdoors, or I clean the soles of my sneakers so that I don't mess up or dirty and degrade the straps while using them.  The better you take care of your equipment the longer it lasts.  Using bare feet could get a little uncomfortable.

**Q: How exactly do you workout your chest with this? Also, is there any way to actually measure your progress?**
A: You can train the chest by shortening it up and positioning it across the back to perform a forward press. This device doesn't really provide a way to measure progress.  It is a relatively cheap and portable isometric exercise device.  It's best use is for travel or a quick workout when pressed for time. Probably not well suited to a stand alone routine.

**Q: Will this work witha Bullworker Classic?**
A: Hello Peter Shmidt,
Thanks for your inquiry. No, the WorldFit ISO Trainer is a stand-alone training device. 
With best regards,
Your WorldFit Team

### ⭐⭐⭐⭐⭐ Awesome product for isometric training
*by P***E on September 6, 2022*

This isometric training strap is very sturdy and well made. The handles are comfortable and the wide strap is long and easy to adjust. It comes with a handy storage bag and short instruction leaflet, too. I can see this strap providing many years of use - it’s bombproof! My only gripe is how much I had to pay for shipping. This is not the manufacturer’s fault, so has not effected my five star rating. However, it cost almost as much to ship as it did to buy. It’s a small, light product and I’ve paid much less for far larger, heavier parcels - like $20 for a pair of hiking boots. That said, I’m very happy with my purchase, so even with the cost of the shipping, this was money well spent.
